mSAP (Modified Semi-additive Process) - a very thin copper layer is first formed on the surface of the PCB material, and then the lines that do not need to be retained are covered with a coating, and the required lines are exposed and are added by electroplating. Then, after removing the coating, the thin copper layer that has not been thickened is removed by micro-etching, and finally the required circuit is formed.
